Whitney's Choice of Emblemes 191a

Spes vana

The eager haulke, with sodaine sighte of lure
Doth stoope, in hope to have her wished praye:
So, manie men do stoope to sightes unsure:
And curteous speeche, dothe keepe them at the bay.
Let suche beware, lest frendlie lookes be like,
The lure, to which the soaring haulke did strike?
